Systems and methods for time-sensitive networking analytics

Abstract

Systems and methods described herein provide an interface for an Network Data Analytics Function (NWDAF) to extract events from a Time Sensitive Communication Time Synchronization Function (TSCTSF) when operators deploy Time Sensitive Networking (TSN) for a given network slice. An NWDAF in a core network receives an information request for a TSN service and sends, to a TSCTSF, a data request based on the information request. The NWDAF receives event data responsive to the data request and generates an analytics report based on the event data.

What is claimed is: 
     
         1 . A method, comprising:
 receiving, by a Network Data Analytics Function (NWDAF) in a core network, an information request for a Time Sensitive Networking (TSN) service;   sending, by the NWDAF and to a Time Sensitive Communication Time Synchronization Function (TSCTSF), a data request, based on the information request, to subscribe to receive TSN quality of service (QoS) statistics from the TSCTSF;   collecting, by the NWDAF and from the TSCTSF, event data responsive to the data request;   segregating, by the NWDAF, the collected event data in a separate analytics environment that is isolated from other network data received by the NWDAF; and   generating, by the NWDAF, an analytics report based on the collected event data, and at least one of:   wherein the information request identifies a TSN slice type, or   wherein the collected event data includes a port state of a Network Side TSN Translator (NW-TT).   
     
     
         2 . The method of  claim 1 , further comprising:
 sending, by the NWDAF, the analytics report to a network function via a standardized interface.   
     
     
         3 . The method of  claim 1 , wherein receiving the information request includes receiving an NWDAF analytics request for one of a request-response model or a subscription-notification model. 
     
     
         4 . The method of  claim 1 , wherein sending the data request includes sending the data request to the TSCTSF via a standardized interface. 
     
     
         5 . The method of  claim 1 , wherein the segregating further comprises:
 directing the collected event data into one of a secure enclave or a trusted execution environment.   
     
     
         6 . The method of  claim 1 , wherein generating the analytics report includes:
 generating the analytics report in an isolated TSN analytics environment of the NWDAF.   
     
     
         7 . The method of  claim 1 , wherein the collected event data includes Generalized Precision Time Protocol ((g) PTP) functionalities of a Device Side TSN Translator (DS-TT) and a Network Side TSN Translator (NW-TT). 
     
     
         8 . A network device comprising:
 a processor configured to:
 receive, by a Network Data Analytics Function (NWDAF) in a core network, an information request for a Time Sensitive Networking (TSN) service; 
 send, to a Time Sensitive Communication Time Synchronization Function (TSCTSF), a data request, based on the information request, to subscribe to receive TSN quality of service (QoS) statistics from the TSCTSF; 
 collect, from the TSCTSF, event data responsive to the data request; 
 segregate the collected event data in a separate analytics environment that is isolated from other network data received by the NWDAF; and 
 generate an analytics report based on the collected event data, and at least on of: 
   wherein the information request identifies a TSN slice type, or   wherein the collected event data includes a port state of a Network Side TSN Translator (NW-TT).   
     
     
         9 . The network device of  claim 8 , wherein the processor is further configured to:
 send the analytics report to a network function via a standardized interface.   
     
     
         10 . The network device of  claim 8 , wherein when receiving the information request, the processor is further configured to:
 receive an NWDAF analytics request for one of a request-response model or a subscription-notification model.   
     
     
         11 . The network device of  claim 8 , wherein when sending the data request, the processor is further configured to:
 send the data request to the TSCTSF via a standardized interface.   
     
     
         12 . The network device of  claim 8 , wherein, when segregating the event data, the processor is further configured to:
 direct the collected event data into one of a secure enclave or a trusted execution environment.   
     
     
         13 . The network device of  claim 12 , wherein, when generating the analytics report, the processor is further configured to:

         14 . The network device of  claim 8 , wherein the collected event data includes clock parameters for a Device Side TSN Translator (DS-TT) and a Network Side TSN Translator (NW-TT). 
     
     
         15 . A non-transitory computer-readable medium containing instructions executable by at least one processor, the computer-readable medium comprising the instructions for:
 receiving, by a Network Data Analytics Function (NWDAF) in a core network, an information request for a Time Sensitive Networking (TSN) service;   sending, by the NWDAF and to a Time Sensitive Communication Time Synchronization Function (TSCTSF), a data request, based on the information request, to subscribe to receive TSN quality of service (QoS) statistics from the TSCTSF;   collecting, by the NWDAF and from the TSCTSF, event data responsive to the data request;   segregating, by the NWDAF, the collected event data in a separate analytics environment that is isolated from other network data received by the NWDAF; and   generating, by the NWDAF, an analytics report based on the collected event data, and at least one of:   wherein the information request identifies a TSN slice type, or   wherein the collected event data includes a port state of a Network Side TSN Translator (NW-TT).   
     
     
         16 . The non-transitory computer-readable medium  claim 15 , further comprising instructions for:
